Abstract: A door locking device includes: a latch mechanism detachably engageable with a striker; an opening lever rotatable interlockingly with a manipulation of a door handle; a transmission member swingable between an unlocking position and a locking position; and a spring member biasing the transmission member from the locking position toward the unlocking position. The spring member allows the movement of the transmission member from the unlocking position toward the locking position in a state where a force of inertia equal to or more than a set value acts on the transmission member. The door locking device also includes a restricting portion restricting biasing of the transmission member toward the unlocking position by the spring member when the transmission member is moved to the locking position against a biasing force of the spring member.

Abstract: A door locking device includes a latching mechanism configured to detachably lock a striker fixed to a vehicle body, an inner lever capable of rotating for releasing locking of the striker by the latching mechanism; and a child lever capable of rotating between an unlocked position where the inner lever is contactable with the child lever and a locked position where the inner lever is uncontactable with the child lever. The child lever is configured to transmit a rotational force of the inner lever to the latching mechanism by being rotated due to contacting of the inner lever with the child lever at the unlocked position.

Abstract: A door locking device includes a latch mechanism with which a striker is engageable or from which the striker is disengageable. A first link operates the latch mechanism in an interlocking manner with an inner door handle so as to release the striker. A second link is movable between an unlocked position where the second link is operated in an interlocking manner with the first link and a locked position where the second link is not operated in an interlocking manner with the first link and operates the latch mechanism in an interlocking manner with an outer handle by way of the first link in the unlocked position so as to release the striker. A locking lever changes over the second link between the unlocked position and the locked position.

Abstract: A door latch device includes a latch mechanism, an inner lever having a connection lever and an actuation lever, and a lock mechanism switching between unlocked and locked state. The lock mechanism includes a connection member capable of transmitting operation of the connection lever to the actuation lever, a first rotating lever rotated by a motor to first and second working positions, a second rotating lever rotatable to a first rotation position where the connection member is moved to an unlock position and a second rotation position where the connection member is moved to a lock position, a connection spring connecting the first rotating lever and the second rotating lever while allowing relative rotation of them, and a holding spring having a biasing force stronger than a biasing force of the connection spring and holds the first rotating lever at the first and second working positions.

Abstract: A vehicle door lock device includes a door handle base provided at a vehicle door and provided with a cylinder lock, and a door latch mechanism provided at the vehicle door. The cylinder lock includes a key cylinder, a paddle portion operably and detachably coupled to the door latch mechanism and configured to transmit rotation of the key cylinder to the door latch mechanism, and a support portion configured to rotatably support the paddle portion. The door latch mechanism includes a key rotor into which the paddle portion is detachably inserted. The paddle portion is supported on the support portion to rotate between a direction of a center axis of the support portion and a direction inclined with respect to the center axis.
